TABLE-PAD.

Specification of Letters Patent.

Patented Sept. 21, 1915..

Application filed. April 8, 1914. Serial No. 830,388.

To all whom it may concern:

Be it known that I, COLEMAN C. LYDoN, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State'of Minnesota, have invented certain new and useful Improvements in Table- Pads; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My present invention relates to so-called table pads for table top protectors, and has for its object to improve the same in the several particulars hereinafter noted.

The invention is illustrated in the accompanying drawings, wherein like characters parts throughout the several views.

Referring .to the drawings: Figure l is a plan view of on of the pad sections with numerous parts broken away. Fig. 2 is a section taken approximately on the line 00 m in Fig. 1; Fig. 3 is a section taken approximately on the line m m in Fig. 1,

and showing portions of the table top to which the pad is applied; and Fig. 4 is an enlarged section taken on the same line as] Fig. 2, but showing the quadrants of the pad sections folded together and showing the edges of the various elements of the pad as much exaggerated.

Of the parts ofthe table it is only desirable to note the two-part or sectional top 2.

The improved pad may be made in various different forms or contours, but as illustrated, in thedrawings, is of circular form and is made up of two separable sections, each of which sections is made up of two quadrants connected together for hingelike folding movements. Each of the said quadrants of the pad comprises as follows:

A pair of spacing bars 3, preferably of wood are secured together at their abutting ends, to form a rectangle or L; and fitting the angle formed between 'the same, is loosely placed a panel 4 preferably made up of two layers of cardboard and an intermediate corrugated cardboard glued or secured together to form a very light, yet comparatively strong and stifi body. Corrugated cardboard material made up of three layers just noted, is found commercially on the market and may be purchased at very small cost. In addition to chcapness, it has'the advantage of being sheet light and of being a good insulator or nonconductor of heat. The panel 4 and spacing strips 3 are of the same thickness, so that their upper and lower surfaces will lie flush. Layers of quite heavy cardboard 5 and 5 are placed above and below the panel 4 and spacing strips 3 and are glued, or otherwise rigidly secured to the said spacing strips, but are not attached to the said panel. A layer of cloth or other suitable material 6 is spread over the cardboard layer 5 and the three edges thereof, are folded over the three edges of the pad quadrants or subsections and are turned under. and'secured to three edges of the cardboard layer 5*. In this way, the panels 4 are loosely incased within a sort of a containing envelop so that'they are held in proper position but not attached to any one of'the elements of the pad. This is important because the said panels will contract and ex-:. pand very considerably under different atmospheric conditions. In practice, it has been found that where similar panels are secured to various other elements of the pad which surround the same, either of the said surrounding elements will be forced out of position, or the panels, under certain conditions, will block or warp the pad out 7 of shape.

' The quadrants or subsections of the pad 7 are connected by a hinge-strip 7 of buckram or other strong flexible material,which overlaps the joint between the same and is secured thereto, by a cement or other suitable material. One face of the pad is preferably made water proof by a layer of oil cloth 8, which, in the pad shown, is of approximately semi-circular form and at its edges is folded over and is cemented, or otherwise uadrantial secured to the edges of two pasteboard sheets 9, that are 0 the same size as the corresponding quadrants above described. For an important purpose, a considerable space is left between the abutting edges of the two pasteboard quadrants 9. The two quadrants 9 are glued, or otherwise secured to the faces of the pasteboard sheets 5 and the oil cloth 8 will then lap the joint quadrants or subformed between the two sections.

When the two quadrants or subsections are folded together, as shown in Fig. 4, a real hinge movement is taken by the joint strip 7, and the-oil cloth at the joint will be folded, as shown, at 8 in said Fig. 4.

Here it will be noted that by spacing the adjacent edges of the cardboard layers 9, as above described, a space is left, when the pad is folded, beyond the edges of the said layers 9 and into which the folded portion 8* of the oil cloth projects and is allowed to bulge or form a loop, substantially as shown in Fig. 4C. This is highly important,

because, in: this way, the folded oil cloth is prevented from being tightly pressed and folded abruptly back upon itself when the pad is folded. In practice,it has been found rangement in which the pad would frequently be employed. when the table cloth is not applied, as for example, when the table is used for playing cards.

,Usually, when the pad is to be used on a dining table with the table cloth spread over the same, the oil cloth facing will be ma tose turned upward, which would bring the water proof face of the pad to the top where it would resist the passage of water or liquids to the body of the pad.

As shown, the pad sections are provided with depending anchoring loops or straps 10, the ends of which, as shown, are insert-- ed and secured between the card board layers 5 and 9. These straps 10 are adapted to be pinched between the abutting edges of the table top, as shown in Fig. 3, and as more fully set forth and claimed in my pending application 789,677 filed September 13, 1913, entitled Table pad.

What I claim is:

A table pad made up of apair of sections connected by a hinge joint and having an oilcloth covering secured to said sections and extending across the hinge joint thereof, the said sections having a clearance space between the hinge joint and oil cloth and into which clearance space the oilcloth, at the hinge joint, is adapted to be folded in a loose condition.

In testimony whereof I allix -my signature in presence of two witnesses.
